  Ah! That's why....

  ftp.kernel.org generally lags behind the PowerPC development tree. For the
latest there are a few sources to choose from. Generally the differences are
based on what people are working on.

  Cort's Tree: www.fsmlabs.com/linuxppcbk.html
  Paul's Tree: linuxcare.com.au/paulus/kernels.html
  My Tree: fsmlabs.com/~tgall

  Take a look at http://linuxppc.org ... very good collection of PowerPC info...

I wouldn't say you *NEED* to run BK, as rsync works just fine.
